IMPROVEMENT IN SPIRIT-STILLS.

Specification forming part of Letters Patent No. 117,445, dated July 25,1871.

and exact description of the same, reference being had to theaccompanying drawing forming a part of this' specification, in which-Figure 1 is a sectional elevation, and Fig.2 is a horizontal section.

This invention relates to an improvement in 'the ordinary columnarstill-cap, composed of a series of cups placed one upon or one besideanother, in each of which redistillation takes place of the liquidcondensed from the vapor sent up into the cap from the still. Theinvention consists in the means hereinafter described, whereby arectification of the spirit is made to take place in each cup of thecolumnar cap at the same time with the redistillation above referred to.

In the drawing, Fig. 1 shows the columnar cap, consisting ofa series ofsepa-rate cups, a,set one upon another, and provided with externalflanges b at their tops and bottoms, through which pass the bolts thatfasten the cups together. Each cup has a diaphragm, c, extending acrossits bottom, through which diaphragm are made holes that communicate withthe bores of two or more vertical tubes, d., which are secured to thediaphragms at their lower ends. The tubes d are open at top and bottom.Inclosing each of them is a tube, c, closed at its top and secured atits lower end to the diaphragm c. Holes e are made in the outside tubese, at their bottoms, above the diaphragms. Across each cup, at asuitable distance above the diaphragm c, is placed a perforated plate,j', having a vertical flange, fl, turned down around its edge, whichflanges f1 rest on rings f2, secured to the insides of the'cups abovethe diaphragms. By means of these rings and flanges the plates f aresustained against any degree of pressure from vapor they are likely tobe subjected to. Through each diaphragm passes an overflow-tube g, whoseupper end is separated by a slight interval from the perforated plateabove. The whole space within each cup above the plate f is filled withcharcoal or other suitable rectifying material, and each cup should beprovided with a man-hole, It, at one side, at top and bottom, to allowof removing and replacing the charcoal as often as it may becomenecessary.

The operation of the apparatus is .as follows:

The vapor that rises from the still into each cup successively passesupward through the tubes d, is turned downward by the tubes e to thediaphragms c, passes through the holes e', and ascends through each cupto the one neXt above, being thus distributed through therectifyingmachine. That part of the vapor that is condensed in each cupis volatilized by the heat supplied from beneath, and its vapor passesupward with the rest. The pipe gis for preventing too great anaccumulation of liquid in anyone cup by affording the liquid an escapeinto the cup beneath before it rises high enough to obstruct theperforations in the plates c. Vhat I esteem as new and of my inventionherein is the means described for rectifying the spirit at the same timeit is redistilled by means of the charcoal in each cup resting on theperforated plate which sustains the charcoal, the said plate allowingthe vapor to ascend into the charcoal and become partially rectified bypassing through it, so that the spirit is rendered purer and purer ateach successive stage of its ascent, and may be rendered entirely pureby carrying the process far enough.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, in each cup a of the columnar still-cap, of thedoubling tubes d e, overflow-tube g, the perforated plate j', and aquantity of charcoal or other suitable material placed above it, asspecified.
